As party in-fighting has overtaken talk of Labour policy in recent weeks, Jeremy Corbyn said he felt vindicated after his re-election as leader yesterday at the official party hustings, and pledged to "wipe the slate clean" with rebel MPs.
Speaking at the party conference in Liverpool, Rachel Reeves, a former colleague of Labour politican Jo Cox, called for the party to heal its divisions in dedication to the late MP, who was killed in a horrifying attack in her home constituency of Batley and Spen in June.
Reeves led a special tribute to the mother of two, which included a short video dedicated to Cox's achievements, and received a long standing ovation and loud round of applause.
Baroness Royall said a moment of silence would not have been fitting for the MP who always spoke up.
Reeves said: "We know that our party and our country face challenging times.
"But as we debate and debate passionately this week, on conference floor and at fringe meetings, we here, all of us, we have far more in common than that which divides us.
"Let's treat each other as friends and as comrades.
"As Jo appealed to our common sense of humanity and of seeing the good in people, I urge you let's live by those values too."
She added: "As I said when I paid tribute to Jo in parliament, Batley and Spen will go on to elect a new MP on October 20 and we wish her well.
"But no one can ever replace a mother. Jo we miss you."
Former soap actress Tracy Brabin, who has been selected as Labour's candidate in the by-election sparked by Cox's death, broke down in tears during the tributes.
